skript help?

[sulf]

Hey guys, i currently have this skript:

on block damage:
    if event-block is barrier:
        if player's tool is pickaxe:
            set event-block to air
            make console execute command "/give %player% barrier 1"

issue is, with this current method, it bypasses worldguard - meaning a player could break, in this case, barriers in places they're not permitted to. How could this be rewritten to disallow this?

You can check the region that event-block is in. And instead of making console execute the command, you can use skript and write 

give player 1 of barrier
